Best Answer: I'd say about 10-15 mins walking at a relatively average pace!! Fastest time to run a mile is around 4 minutes. The average time to walk a mile is 12 minutes, so half a mile would be 6 minutes. i walk a mile every morning in 15-20 minutes, so probably 10 minutes. At a semi rapid rate about 7 1/2 minutes.
Allergy is one of the most common causes for burning sensation in nose. It can be a seasonal allergy or an allergy associated with pollution. Certain gases and smoke released from chemical substances may pollute the air and find their way into the nose and air passages.
Nasal cannulas may cause mild discomfort or nosebleeds in some cases. One common problem is that the forced oxygen flow dries out the nasal passages. While oxygen is not flammable, it can feed a fire and make it much worse quickly.
